![]() Under the intense pressure and heat from a fire, most intumescents work by producing a foam-like substance, from the chemicals in it reacting and releasing a vapour. Intumescent coatings are generally available as water-based or solvent based variations (more information below). The top coating produces a light char as it is burnt, which makes it a poor conductor of heat and fire spread.Īpplication of intumescent paint layers helps fireproof structural steel, steel beams, steelwork or cast iron and can be used externally or internally, on small or larger areas. As the intumescent layer swells up, it increases its surface volume, which then helps to decrease the intensity of the flames. Intumescent coatings are passive fire protection measures which swell up when heated (in a fire for example) and protect the material (steel, plasterboard or wood ) underneath it, from fire.
